Models with workflow state "default" are only considered in composition if no
other valid model is defined. This allows to implement "ingest anything"
policy in wendelin.

If mapping is not a dict, we store a message that would fail later when
being viewed, typically breaking History tab when used in workflow
history.

Instead of displaying the same ImportError without any detail for both
cases of a non existant module or of an existing module which cause
error during import, improve the second case by displaying a different
message containing the original traceback.

The pattern of using > will start by erasing the file, so if mysqldump
does not run to completion developer will loose the previous dump, but
in such case, that previous dump was better than nothing.

User is usually interested by last movement in stock, not by several
months/years old movement. Thus display first fresh movement, and user
could then go to next pages to see oldest movements if needed.

added zope2 compatibility, but nexedi/erp5@21f85a6f (comment 180420) noted
the given assumption isn't true, which is why fixup commit nexedi/erp5@7a2c616e was
added. But nexedi/erp5@21f85a6f (comment 184548) noted
that nexedi/erp5@7a2c616e missed one case,
which is why this fixup commit is added. Now everything should be ok.

Because these two plugins implement the refresh of the authentication
token (unlike the facebook plugin), we can use a longer cache here.
With the previous value of 1 day, when not using the site for more than
1 day, token would expire from cache and user have to authenticate again.
Because the scenario of "access is revoked from authorization server"
is handled by refreshing the access token, we can use a longer duration
here, so that user do not have to login again after not using for two
days.

After server restarts, mariadb uses an error 1927 which is mariadb
specific, with no corresponding constant in CR module when server
restart. This is the case at least with mariadb 10.3.38.

This fix the following problem:
 - start zope and use mariadb connection
 - restart mariadb
 - use mariadb connection again, see an error:
    Error Type: OperationalError
    Error Value: (1927, 'Connection was killed')

This change to treat 1927 as an error for which we can reconnect and
retry the query. Some other connectors do it, for example sqlalchemy in
https://github.com/sqlalchemy/sqlalchemy/issues/5493

This prevents tracebacks during shutdown:

Also rename the method because this is not longer *Z*server.

This waitress close() API is not public part of API, so we still ignore
the case where the server thread does not stop after 5 seconds. This
happens if some HTTP connections are still open at the end of test.

This is supposed to be catched by an external validator on the field,
but checking the one more time here supports custom dialogs where there
might not be form level validation.

to indicate success or failure

Also add a code comment about the changes from e50e45e4 (erp5_core:
Password Tool should not leak info on users, 2020-12-30), because while
looking at this code it seems there was a mistake here.

It was wrongly named password_confirmation in some places and this was
silently ignored because the parameter is not used at the moment and
because of **kw in the signature.

This is a preparatory commit so that we can check that the password and
the confirmation match

Rewrite to not use legacy "Sequence", some python3 fixes, use urllib
to assert URLs, use more consistent passwords.

Also extend coverage a bit: check that the email contains the key, check
that login lookup does not use catalog search syntax.

There is no zmi_icon on Zope2.

   This is expected that constraints can call getConstraintType() if they are filtered:
